pybind11: Robot& parameter conversion fails in Python 3.10 but works in 3.8

[lin19970227]

I have a C++ Robot class that is non-copyable and non-assignable. I've exposed it to Python using pybind11 as a Robot module. I also have another C++ class MassageBtManager with a constructor MassageBtManager::MassageBtManager(Robot& robot), which I've separately exposed as a massage_bt_pybind module.

When I initialize a Robot object in Python and try to pass it to initialize a MassageBtManager in Python 3.10, I get a conversion error, but it works fine in Python 3.8. How should I modify my MassageBtManager binding to make this work properly across different Python versions?

I modified it to the one shown in the above picture. Although it can call an interface, the program will immediately segment a fault

Module A: Define the Robot class and instantiate it in Python.
Module B: Define the MassageBtManager class and receive a reference to the Robot object.

If I use py::init<flexiv::rdk::Robot&>(), Python 3.10 prompts that flexivrdk.flexivrdk.Robot cannot be converted to flexiv::rdk::Robot.
